摘要
变速恒频风力发电机在工作过程中会产生谐波,当双馈异步风力发电机风速达到切入风速时,并入电网的双馈异步风力发电机与其他直驱永磁风力发电机之间会因为功率传递产生谐波扰动,文章研究分析了此问题,并根据瞬时无功理论和其他风力发电有关理论在Matlab中进行建模和仿真,仿真结果表明亚同步发电状态双馈异步风力发电机会因为功率传递受到正常工作直驱风力发电机的谐波扰动,扰动会随着风力发电机数量的增多而加剧。
There are harmonics when VSCF wind power generators are running. Harmonic interference is caused by power flow between some direct-driven permanent magnet wind turbine generators （I）- PMWG） and other doubly-fed wind power generators （DFIG） that are connecting to grid when they reach the cut-in wind speed in a wind farm. According to the theory of instantaneous reactive power, a model of internal harmonics between VSCF wind power generators in wind farm is established in Matlab, the result of simulation shows that power flow between doubly-fed wind power generator in sub- synchronous condition and direct-driven wind power generator will cause harmonic interference that will exacerbate with the increase in the number of wind generators.
